Outstanding Web Features: The Global Fishing Watch platform is built around three core components: a Fishing Activity Map, Vessel Tracking Data, and Research. The map is based on data generated by the Automatic Identification System (AIS), a satellite-powered tracking system that broadcasts the location of all AIS-enabled vessels as a way to prevent collisions at sea. By analyzing the identity, speed, and direction of vessels that use AIS (minus cargo ships and other non-fishing vessel activity), the platform is able to show apparent commercial resource extraction that takes place on the open ocean. Visitors to Global Fishing Watch can learn more about the platform and the data that powers it before they check out the interactive map, which is searchable, editable by "layers," and offers a number of filters. Visitors can also register to access or download the raw data that powers the public platform, learn more about the platform's ongoing transparency initiatives, access a list of related publications, and learn how they can make a difference and/or other spread the word.
